CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 614,663, dated November 22, 1898.

Application iiled February 7,1898. Serial No. 669,380. (No model.)

T0 all whom, it may concern.-

Beit known that I, GUsTAv lI. LIPPMANN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Oar-Couplings, of which the following is a specication. Y

My invention relates to improvements in 1car-couplings of the Janney type; and it consists in certain novel features hereinafter dcscribed and claimed.

In the annexed drawings, which fully illustrate my invention, Figure l is a view, partly in plan and partly in horizontal section, showing the locking-block raised to permit uncoupling and the knuckle. swung partly forward. Fig. 2 is a longitudinal vertical section showing the knuckle in its coupled position and locked, with the locking-block raised in dotted lines to indicate its position when it is desired to permit the cars to come together without coupling; and Fig. 3 is a detail view of the locking-block and the catch for holding it in its inoperative position.

The draw-head A and the knuckle B are of the usual construction and need no detailed description herein. At the rear of the drawhead I journal the transverse slidable shaft C, which extends to one side of the car, where it may be `provided with any suitable handle for its manipulation. A rod or chain may be connected thereto and extend to the top of the car, so as to permit the coupling to be operated from the top of freight-cars, as will be readily understood. \Vithin the drawhead I secure to this transverse shaft a locking-block D, which is adapted to be dropped into the path of the tongue on the knuckle, as will be readily understood on reference to Fig. l, and thereby prevent movement of the knuckle, and consequently hold the couplings in engagement. In the under side of this locking-block and near one edge ofthe same I form the longitudinal groove E, which is adapted, when the block is moved laterally, to engage an inclined rib or catch F and be thereby held in an elevated position to permit the knuckle to swing freely, so that the cars may come together without being coupled.

My present device is very simple and cheap 5o in its construction and efficient in operation. lVhen the locking-block is not held in its raised position by the catch, it will positively prevent the knuckle from swinging forward so as to uncouple the cars, but will permit the knuckle to swingin so as to effect a coupling, thus making the operation of the device entirely automatic. If it be desired to uncouple the cars, the. operator at the side of the car simply turns the transverse shaft so 6o as to raise the locking-block and the cars are thendrawn apart. If it be desired to have the cars come together without coupling, as in making up trains and sidetracking, the shaft is turned so as to raise the lockingblock and is then drawn laterally so as to engage the said block with the catch.

The rear end of the knuckle-tongue is of course beveled, so that when the cars are coupled automatically it will cause an oscil- 7o lation of the locking-block without any transverse movement thereof, therebypermitting the tongue to move under and beyond the block, after which the block will drop into position and lock the knuckle against a re- 75 verse movement.

I prefer to employ the grooved construction of the block and the narrow rib-catch illustrated, as accidental lateral movement of the block is thereby prevented; but it is 8o entirely within the scope'of the invention to employ a Hat-faced block and catch, the block being held by simply resting on the catch.

It will be observed that the catch is on the floor of the draw-head, in rear of the transverse shaft, so that boring of the draw-head is obviated, and there are no holes in the top of the draw-head to permit the entrance of rain. Corrosion of the working parts is thus avoided.

I do not wish to restrict myself to the details as described herein, as any or all parts may be modified without, however, departing from the principle of my invention. p

Having thus described my invention, what 95 I claim, and desire to secure by Letters Patent, is-

In a car-coupling, the combination with the drztvwheztd and the knuckle swinging' therein, of :L sldable transverse shaft mounted in the draw-head, a rib or Catch on the Hoor of the drmwhead in rear of the said shaft, and a, looking-block on the shaft having; a groove in its under sido adapted to engage the said rib 01' catch.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

GUSTAV II. LIPPMANN.
